To all whom, t may concern.L

Be it. known that I, ROLLIE B. FAGEOL, a citizen ofthe Unit-ed States'of America, and a resident of Des Moines, Polk county, Iowa, have invented a new and useful Gas-Burner, of which the following is a specification.

The object of this invention is to provide an improved construction for vapor-burners employed in the boilers of automobiles, motor-carriages, and the like.

My invention vconsists in the construction, arrangement, and combination of elements hereinafter set forth, pointed out in my claim, and illustrated by the accompanying drawings, in Which- Figure 1 is a horizontal section on the indicated line 1 1 of Fig. 2. Fig. 2 isa vertical section approximately centrally of Fig. 1.

In the construction of thedevice as shown the numeral 10 designates a bottom plate of circular form and preferably made of sheet metal. The bottom plate 10 has its marginal Aportion stamped, pressed, sWaged, or turned upward and outward to form an annular peripheral iiange 11 in a horizontal plane above the depressed body portion of said plate. A top plate 12, a counterpart of the plate 10, is mounted in opposition thereto, With its peripheral flange 13 in contact with the peripheral iange 11. A ring 14 is positioned below and in contactwith the peripheral flange 11l on the bottom plate 10, and the flanges ll 13 are connected rigidly, such as by rivets, and rest on said ring. Alining apertures are formed in the plates 10 l2, and lues 15, formed of tubing circular in cross-section and with their end portions reducedin exterior diameter to form shoulders thereon, are mounted with their reduced end portionsin said apertures and riveted, swaged, expanded, and closed upon the outermost portions of said plates. Thus air-tight and gas-tight joints are formed between Vthe end portions of the flues and the plates traversed thereby, and at the same time iianges are formed on the extremities of said flues in engagement with the plates, whereby said plates are held rigidly in parallel relations to each other and prevented from separation. In prior structures of this type it is common to merely expand the ends of the iiues in the apertures of the apertures.

formed in the plate 12 around and spaced of the plates without forming shoulders on the lues or riveting the ends of the lnes rigidly on the plates. In such old construction `the excessive heat generated in Vthe burner bases to sustain the plates, and the riveting of the lines rigidly on the plates closes the joints against the shoulders and expands the flue ends to close the joints against the Walls A row of gas-ports 16 is from each of the flues. I form the gas-ports 16 of larger diameter than those heretofore constructed and provide fewer of them, thus maintaining approximately the same ratio of capacity of the gas-ports in respect of the capacity of the lines and at the same time providing for the economical and eflicient employment of my improved burner under low pressure-that is to say, that heretofore gasburners of this type have Vemployed small gas-ports in the top plate and force the gas through said ports under an air-pressure of Aabout fifty pounds in the gasolene-tanlz,Where as I am enabled to employ my device successfully under an air-pressure in the gasolenetank of approximately twenty pounds, thus minimizing the danger of explosion and at the same timepreventingclogging of the gasports with sediment. y Y

An aperture is formed in the riin portions of plates 10 12 'by swaging and pressing at points 17 18 to produce a collar, and a mixing-tube 19 is mounted through said collar andaperture and extends-beyond the center diametrically of the burner. The inner end of the mixing-tube 19 opens against one of the iiues 15, which flue serves as a deiiector and spreads the gas within and insures the mixture thereof with air in the burner. The

mixing-tube 19 and burner would be employed in conjunction with a nozzle (not shown) of any desired construction.

A boiler 20, provided with vertical fines 21, is formed with peripheral ears 22 on its lower end portion, and said peripheral ears Sgo IOO

are riveted or otherwise rigidly secured to the bottom of said boiler, the iiues being rigidly mounted in said bottom.

A burner-casing is provided and formed of sheet-metal rings 23 24, concentric with each other, and the space between the said rings is filled with asbestos-cement 25. The lower end of the burnercasing is rigidly connected to the ring 14, and the bottom of the boiler rests on and is sealed by the cement to the upper end of said casing. A supply-pipe 26 leads from a gasolene-tank (not shown) of common form and extends through the wall of the burner-casing across the interior of said casingn-d into communication with the lower end of onelOf the boiler-dues. The up per end of the boiler-due, connected at its lower end to the supply-pipe 26, is connected in any suitable manner to the upper end of another boiler-[ine 21, diametrically opposite thereto, and the latter Hue is connected at its lower end to ,a vapor-pipe 27, which extends across the interior of the burner-casing and through the wall thereof diametrically opposite the point of entrance of the supplypipe 26 and communicates with the nozzle (not shown) whereby the mixing-tube is fed. Thus it will be seen that the gasolene or other vaporizing iiuid is led by the pipe 26 across the burner-casing above the burner, is passed through i'lues'in and across the top of the boiler, and is again carried by the pipe 27 across the face of the burner and in proximity thereto before being discharged through the nozzle into the mixing-tube. Provision is hereby made for completely and perfectly vaporizing gasolene or other fluid prior to its introduction to the mixing tube. At the same time such arrangement provides a convenient means for initiating the operation of the burner, since it is possible to introduce an alcohol-burning torch within the burnercasing and apply initial heat directly to those portions of the pipes 26 2,7 within the burnercasing, thus readily and conveniently performing the operation of preliminary creation of vapor to be fed to the mixing-tube. Strainers 28 29 are mounted in a common manner in the boiler-fines traversed by the Vaporizing Huid.

I claim as my invention'- A burner, comprising the plates formed with alining apertures, flues formed with reduced end portions tting snugly i-n said apertures and having their extremities riveted on the outer surfaces of the plates, the upper plate having gas-ports formed therein in rows surrounding the upper ends of the lines, a mixing-tube entering the gas-chamber and means for supplying Vapor to said mixing-tube, the inner end of said mixingtube opening against one of said fines Whereby the vapor discharged from said tube is spread and distributed throughout the space between said plates.
